T0 all whom it may concern:

Be it known that I, HERMANN WINTER, of the borough of Brooklyn, of the city of New York, in the State of New York, have invented certain new and useful Improvements in Drilling and Nailing Machines, of which the following is the specification, reference being had to the accompanying drawings, forming art hereof.

In suc apparatuses as drilling and nailing machines for attaching electrotype plates, zinc etchings Sac. to wooden blocks, and for various other purposes, it is always desirable that the machine shall stop after each complete cycle of operation, so that the work in the machine may be properly adjusted. For this purpose, these machines and machines of like general character are provided with a clutch arrangement to stop the machines at the proper time, which clutch arrangement is under the immediate control of the operator who, when he has adjusted the work, starts up the machine again.

In. drilling and nailing machines, it is particularly desirable, with some kinds of work, that drill spindles shall have ample time to drill a hole of sufficient extent to permit relatively long nails to be used.

It is therefore the object of this invention to provide a clutch which shall be capable of operating automatically in machines of this sort to permit the drilling to continue while the rest of the machine is at rest, and to start the machine again at a predetermined time that is, when the drill shall have completed a hole sufficiently large for the purpose in hand.

In the drawings, a drilling and nailing machine, in which the clutch improvements may be embodied, is sufficiently illustrated to enable the application of the improvements to be understood, and the improvements are also illustrated in detail.

In said drawings, Figure 1 is a side elevation of the drilling and nailing machine, Fig. 2 is a front elevation of the same, Fig. 3 is a detailed sectional view of a portion of the machine on a larger scale taken on the plane indicated by the line 3 3 in Fig. 2, Fig. 4 is a view partly in elevation and partly in section of a portion of the machine showing the application of the clutch thereto and its position adjacent to the driving pulley therein. Figs. 5v and 6 are views in elevation of the general character of the machine illustrated in the drawings, in order to enable the application of the improved clutch thereto to be' readily understood. For the details of construction of such machine, reference can be had to Letters Patent of the United States No. 791,287, dated May 30, 1905.

The work is supported on a suitable table 13 which surmounts a stand 12, the latter being ordinarily just high enough to bring the work into a convenient position for manipulation by the operator while standing up. Directly over the work and mounted side by side are the drill, and its spindle 30, part of the nail delivering mechanism 58, 74, 75, and the hammer 86. The spindle, hammer and the parts of the nail delivery mechanism referred to are carried by a reciprocating plate 15, which has flanged portions 16 and 17 overhanging respectively the upper and lower portions of the end 14a of'a standard or support 1-1 which rises from the stand 12. By this means and through the operation of a crank pin 22 on the shaft 20, as is afterwards explained, the spindle with its drill and the hammer and nail delivering mechanism are shifted, so that the spindle after drilling a hole may be moved laterally and the block 75, through which the nails are delivered and through which the hammer drives, may be brought over the hole drilled by the spindle. The spindle is driven through a belt 33 engaging its pulley 34, which belt passes around guide pulleys 35 and thence down around a ulley 36 on the lower part of the stand and 1s lowered and raised between successive shiftings of the carrier, so as to rest down upon the workand then be raised above the work, v

to which the driving pulley 23 is secured.y

The carrier may be reciprocated by means of a crank pin 22, rotated by the main shaft, engaging the walls of an irregular slot 26 in said carrier. The nails which slide down 5 from a magazine 5() along an inclined track 51 are fed one by one into the tube 74 by a tubular block 57 having a hooked portion, the tubular block being` oscillated by the reciprocation of the carrier plate. The hammer is driven by an arm 87 (Fig. 3) to which it is secured, said arm projecting forward from a reciprocating plate 88 sliding `in a channel in the rear face of the carrier plate 15. Said plate 88 is reciprocated by the crank arm 22 engaging a slot in the same. These several mechanisms are preferably timed, so that'one revolution of the shaft 2O effects the shifting of the carrier to bring the nail delivering mechanism and hammer into proper position, the operation of the nail delivering mechanism and hammer and the returning of the carrier plate to its first position, that is just one cycle of operations.

In order that the mechanism may come to a stand-still after each complete cycle of operations, so that the work may be re-arranged in the machine and by mechanism the drill spindle is not necessar-ily included), `a clutch is provided for the main shaft and may be controlled from a foot lever 24 through the medium of a connecting rod 25.

The clutch is preferably constructed to permit the shaft 2O and all the operative parts of the machine controlled through the shaft 20 to rest for a predetermined time after the s indle is brought down upon the work, whife the drill spindle is continued in rotation through the belt 33 and the pulleys 34, 35 and 36, all as heretofore explained. This, as will be obvious, will allow the spindle to be Loperated to perform its drilling while all the other operative parts of the machine are for the time being stopped. For this purpose, one of the members of the clutch may consist of a driving pin 90 secured in any suitable manner to the driving pulley, the driving pulley in this case together with the in 90, constituting the driving member of t e machine; while the other member of the clutch is preferably contained in a collar 91, which is made fast, by any suitable means, to the driven member or shaft 20. Within this collar and constituting a part of the clutch are two -keys 92 and 93 respectively, the latter of -which is somewhat longer than the former and both of which are normally urged outward from the collar into the range of the driving member or pin 90 by suitable means such as springs 94 acting against pins 95 on the keys. The inner ends of the keys are hooked, as shown, and at certain points in the revolution of the shaft 20 engage with means such as cams 96, 97 and 98 respectively, whereby they are drawnout of the range of pin 90 and are so held until they have passed these cams. These releasing cams are preferably constructed as shown in Figs. 7 8 and 9, the cams 96 and 97 being exactly alike while the cam 98 is as much thicker than the cams 96 and 97, or in other words its eXtreme rise is as much higher than the corresponding rise in cams 96 and 97 as the pin 93 is longer than the pin 92. ln this way as the key 93 passes the cams 96 and 97 it will not be drawn completely into the collar 91 and hence it will not be drawn completely out of `the range of the pin 90, while the key 92 in passing any of the cams will be drawn out of engagement with the pin 90.

ln order to effect the desired timing ofthe operation of the drill with respect to the operation of the rest of the machine, the keys 92 and 93 are placed substantially 90 -degrecs apart, and the cams are also placed substantially 90 degrees apart. Furthermore, the cams 97 and 98 are stationary while the cam 96 is connected with the foot lever 24 through the connecting rod 25, and the `operation of the clutch is as follows:

vWith the parts in the position shown in Fig. 5, the foot lever is actuated, thus drawing cam 96 away from the key 92, the latter immediately projecting itself into the range of the continuously rotating pin 90, by which it is engaged and through which it causes the rotation of the shaft 2O in the direction of the arrow. As soon as the shaft has been turned through a quarter of a revolution, or substantially 90 degrees, the key 92 is brought into engagement with the cam 97 which draws the key back into the collar 91 out of the range of the pin 90 and permits the pulley 23 with the driving pin, to continue rotating while the shaft and .all the operative parts which it controls are at rest. The key 93, however, which, when the shaft commenced to move, was in engagement with the cam 98 and was thus drawn completely out of the range of the pin 90, has been brought by the first quarter revolution of the shaft 20 opposite the cam 96, and in engagement therewith. The cam 96, however, is not thick enough to withdraw the key 93 wholly from the range of the pin 90 and accordingly the pin 90, after leaving key 92 will revolve about three-quarters of a revolution until it engages (Fig. 6) the pin 93. rlhis yengagement `then effects a further rotation of shaft 20 through about threequarters of a revolution, when the key 93 will be engaged again by cam 93 and completely withdrawn from the range of pin 90. This, as is obvious, will bring the clutch parts to their initial position, shown in Fig. 5, in which they will remain until the foot lever 24 is again operated. ltwill be seen therefore that when the crank ypin has moved through about 90 degrees, which involves substantially a quarter of a revolution of the shaft, all the operative parts of the machine except the drill spindle will become motionless until the driving pulley has moved through a further three-quarters oi a revolution or thereabouts. During this three-quarters of a revolution, the drill spindle being driven directly or continuously from the driving pulley, that is not through the medium of a clutch but through belt 33, and pulleys 34, 85 and 36, is in operation. At the completion of this three-quarters oi' a revolution of the driving pulley, during which the shaft 20 is at rest, theclutch mechanism will be operated and through the operation of said mechanism the rest of the machine will be started and will continue in operation until the shaft 20 is rotated through three-quarters of a revolution, thus making one complete revolution of the shaft 20 and thus completing one cycle oi' operations of the parts controlled through said shaft.

It will be understood, that, as in all clutches, it is immaterial which member of the clutch is secured to the driving member and which member of the clutch is secured to the driven member and accordingly, although for purposes of convenience in construction the clutch collar 91 is shown connected to the driven member, it will be obvious th at the invention is not limited to this particular construction.

I claim as my invention:

l. In a drilling and nailing machine, the combination with a drill, of a driving member directly connected to drive said drill,

mechanism to move said drill laterally'7 and a clutch to operate said moving mechanism, said clutch including means substantially as described to operate said moving mechanism to bring the drill into position for drilling to allow it to remain in such operative position a predetermined time and permit it to return to its normal position.

2. In a drilling and nailing machine, the combination With a drill, of a driving mem-- drilling, allowing it to remain in such o erative position a predetermined time an to return it to its normal position.

3; In a drilling and nailing machine the combination with a drill, of a driving member, directly connected to drive said drill, mechanism for supporting and o erating said drill, a clutch to operate said mec anism, said clutch including means substantially as described to operate mechanism to bring the drill laterally into position for drilling, allowing it to remain in such operative position a predetermined time and to permit it to return to its normal position, and means for initially engagingsaid clutch and driving member.

4. In a drilling and nailing machine, the combination with a drill, of a driving member, a carrier and lever 'for moving the drill into and out of operative position, and a clutch to operate said carrier and lever, said clutch having two keys adapted to engage the driving member, and means for initially engaging the clutch with the driving member, whereby when a clutch is once engaged it will automatically operate to bring the drill laterally into position for drilling, allowing it to remain a predetermined time and restore it to its normal position in a single cycle ol operation.l
